Well back in gen 1, no dark types and psychic was good against ghost (coding error).

Only bug moves were very weak. Not to mention that mewtwo essentially had a base 154 special attack and special defence (since it was just 1 stat). With amnesia (basically 2 calm minds back then) along with psychic, it was so broken that I could argue that it’s better than mega rayquaza now.
